Fuel freezing point measurement
Hi everyone !
I have been reading this forum for a long time now and here is the day I post my first questions !
This is about a very interesting article published by Boeing about Polar route operations ([FONT='Arial','sans-serif']http://777cheatsheets.com/resources/Safety_Polar_Route_Operations.pdf)[/FONT]. The part about cold fuel management mentions a procedure for estimating the freezing points of blends of Jet A and Jet A-1 without describing it.
Do you have more idetails about this procedure ? How long does it take normally, I mean, can this procedure be applied after each fuel uplift without delaying the flight ? Is it applied to each fuel tank or only to the most critical fuel tanks (i.e. outer tanks) ?
Thank you very much for you answers !
